425-year-old Austrian bell foundry survives on 3D printing and lasers

Wearing protective gear to shield from the extreme heat of molten bronze, workers at one of the last bell foundries in Europe are casting bells weighing several tons.

One after another, the artisans carefully pour the molten metal into specially shaped molds held together with steel bands to create 12 bells for churches in Italy, Germany and Romania.

Founded in 1599, the Grassmayr Bell Foundry, in Innsbruck, western Austria, has survived wars, famines, epidemics and economic challenges.

These days, the family business is run by brothers Johannes and Peter Grassmayr. During the Renaissance in the late Middle Ages, there were hundreds of bell makers in Europe, while today only a handful remain across the continent.

The Grassmayrs’ secret to success: tenacity combined with innovation, such as 3D printing, scanning, lasers, and computer simulation apps.

“Certain things are just like they were 400 years ago. But we innovated a lot. Especially within the last 20 years, we’ve changed a lot,” Johannes Grassmayr told The Associated Press.
